Rhodan, God of the Summons

"Holy vestige, I bring Rhodan's hand onto thee, and beckon for you as tribute to the great Repenter. Arise as a physical form for my lord, arise!"

- Cultist using Rhodan's boon to aid in her summoning ritual.

A being of pure celestial light, Rhodan is the God of the Summons. An abstract being, akin to the likes of Paradime, God of the Division , Rhodan's purpose as a deity is to do with summoning. His status as a Greater Deity due to how abstract the form of worshipping him was meant that practically anybody who used a summoning circle or teleportation circle would essentially have worshipped him. The Being between Worlds, a title known for those that often worshipped him outside of using his runes for summons, is a benevolant being who had never directly interacted with mortals. His business only concerned raw magic itself along with his fellow Gods. This does not stop himself from being a divine being for clerics and holy warriors to use as a source of their prowess. 

Rhodan, whilst not always having a physical form, takes on a faceless, expressionless form compromised of a masculine figure and six wings. The six wings originate from one of the common additions to summoning circles to gain Rhodan's blessing, wing-like appendages overlapping one another in a circular formation, often placed within the centrepiece or smallest circle found within the complete summoning circle. Although, the connection made between Rhodan and a Summoning Circle can only be done if the material used in the circle is red. Many believe this to be a reason as to why demons and other fiends are more likely to be summoned with a sacrifice of blood. The reason for this colour is due to the colour of Rhodan's skin, which is luminescent and also red. 

Uniforms for those who worship Rhodan are similar to the outfit that he is depicted to wear. It commonly follows the key idea of his vibrant reds along with strong golds and yellows, often in robes for those that are members to clergies, but Summoners are often found to don a less conservative outfit due to the more wild nature of their worship and existence within Aitso. 
In modern uses, past the time of the Old Gods and into the age of New Gods for Aitso such as Sol, Rhodan's survival through the purging of his physical form has let his divinity linger on across those who chose to actively worship him. This transference has been put up to excuse by the New Gods as to Rhodan's excess energy being passed to his woshippers, but the true explanation for this occurrence was that Rhodan had sacrificed himself in order for his followers to be given proper power. His essence lives on through the leylines found on summoning circles, allowing him to exist in a state only fit for an observant consciousness, just as Rhodan once was.
